Low Price Chemical Dosing Systems made in China. A chemical dosing system is a facility for automated injection of reagents into a wastewater network for the control of septicity and odour emissions. These systems are typically used at pump stations, sewer manholes, and rising mains. However, they can be installed any place where odour containment is required.

PAC Dosing Systems is the process of adding or administering an amount of PAC into a specific volume of water. It is important to be able to accurately control the ‘dose rate’ for two reasons. Firstly, to ensure there is enough PAC to provide effective treatment. Secondly, to avoid unnecessary wastage of PAC through ineffective dosing practice or spillage. Our PAC Dosing Systems solution, Trans PAC has been developed to offer a flexible, practical solution to PAC Dosing.

High Pressure Metering Pump's operating principle: Reciprocation of plunger drives hydraulic oil, and hydraulic oil drives the diaphragm to reciprocate, so as to suck in and discharge the medium.

Find a huge selection of Ammonia Solution Dosing Pump from China at Dongkai. Ammonia Solution Dosing Pump's working Principle: The motor drives worm gear pair; through eccentric mechanism, rotary motion of the motor is transformed into reciprocation of slide bar. Reciprocating slide bar directly propels mechanical diaphragm to make cyclic deformation, so as to suck in and discharge the medium....

Dongkai is a professional leader China Bladder-Type Dampening Device manufacturers with high quality and reasonable price. The Bladder-Type Dampening Device could be considered as the most traditional and widespread dampener, since it offers a great performance and is manufactured in a very wide range of sizes and building materials. Competitive in price, it is also easy to install. It is specially indicated for clean liquids without suspended solids and of low viscosity. It is manually adjustable and usually installed together with back pressure valves to guarantee the correct pressurisation of the air chamber in relation to the working pressure of the pump, being this assembly very common in diaphragm or piston metering pumps.

Our Metering Pump Check Valves For Industrial Applications​ products are recognized and praised by customers all over the world with excellent quality and good reputation!
